'LAMP-SHADE.

Specification of Letters Patent.

Patented J une 8, i915.

Application led January 23, 1915. Serial No. 3,977.

T0 all whom it may concern Be it known that I, DAVID ROSE, a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania., have invented certain new and useful Improvements in Lamp-Shades; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention relates to lamp shades, and more particularly to an improved collapsible lamp shade, for use with either an oil or gas burner or an electric light.

The main object of the invention is to provide a collapsible shade which, when opened and in use, will not expose -to view any form of adjusting device, but will present a symmetrical and attractive appearance, and when closed and not in use, will occupy a very small space, so that it may be set aside and out of the way, without being liable to beV turned over and broken by contact therewith, which is incident to the use of lamps with shades of the non-folding type as ordinarily constructed.

Other objects are to provide a collapsible lamp shade of the character referred to consisting of few parts compactly arranged in cooperative relation to each other, and which shall be simple in construction, inexpensive in manufacture and efficient, strong and durable in practical use, possessing all of the advantages of a collapsible shade, without the disadvantages and marred appearance due to exposed adjusting devices, and other objectionable features of the latter class of shades as heretofore constructed.

rihe invention will first be hereinafter more particularly described, with reference to the accompanying drawings, which are to be taken as a part of this specification, and then pointed out in the claims at the end of the description.

In said drawings; Figure 1 is a side elevation of an electric lamp with a lampshade embodying my invention mounted on the lamp post or standard; the fabriccovered frame-work of the shade being shown partly in vertical sectional elevation and partly in full lines, in the position occupied when the shade is opened; Fig. 2 is a similar vertical sectional elevation showing the shade closed; Fig. 3 is a side elevation of an ordinary kerosene oil lamp having a lamp shade embodying my invention mounted thereon; Fig. 4 is a similar view of an ordinary lamp with a gas burner having my invention applied thereto, and Fig. 5 is a view similar to Fig. l of a modification of the invention.

Referring to said drawings, in which the same reference letters are used to denote corresponding parts in dierent views, the lamp post or standard A has a base ring or plate B fixed thereon in any appropriate manner, preferably removably secured on the upper end of the standard' so that it may be readily detached and re-placed at will. A top ring or disk C haspivotally secured thereto at their inner ends a series of radially projecting ribs c, preferably elastic, to which are pivoted near their inner ends a corresponding series of stretchers c1, which are hinged at their lower ends to the base plate B. The top and bottom rings or plates B and C are connected, preferably by means of telescopically connected rods D and tubes E, in such manner as to permit the top ring vto be raised and lowered, for the purpose of opening and closing the shade. The rods D, mounted upon the base plate B, may have their lower ends firmly secured to or formed integrally with said plate, and are provided with spring catches d, d, which areyadapted under pressure to recede into recesses in the rods in which they are secured, and allow the frame-work of the shade to collapse and occupy the position shown in Fig. 2 of the drawings, and to protrude throughslots in the tubes E when the pressure is removed so as to secure and hold vthe telescopically connected members in a fixed position with the lamp shade open, as shown-in Fig. 1. The fixed and movable telescopically connected rings or plates and the several ribs and stretchers together form a collapsible frame-work, which may be provided with a cover F of fabric or other suitable material, preferably having `an Vornamental appearance, or of such design as will' produce a pleasing effect to the eye, and the ribs which support the fabric are preferably elastic and ybendable at an intermediate point so that the cover will droop gracefully along the margin thereof when the shade is open; and in this position the resiliency of the ribs will tend to cause the shade vto collapse, ex- A,

erting suflicient pressure to force the top ring unwardlv when the tubes in are released by the catches on the rods D, and therebv contract and close the shade. W hen the shade is closed, pressure upon the top ring will cause it and the tubes E to move downwardly until the spring catches are brought into engagement with the slots in the lower ends of the tubes, in which position the shade will be open and locked, but when said catches are again released the spring pressure exerted by the ribs on the cover will automatically raise the top ring and close the shade.

To give the lamp shade a more ornamental and attractive appearance than if the fabric extends straight across the top plate, a post Gr may be mounted upon the cap C within a sleeve g, which is flanged at its top, and the central portion of the fabric made conical in form with its free end secured between said sleeve and a clamping ring on the upper end of the sleeve below said flange.

lf desired, stiff ribs may be used, according to the form of the shade or cover, and the center of the cover need not be raised, in which case the post Gr and sleeve g may be dispensed with. But the ribs are preferably resilient or exible, and the fabric secured thereto in such manner that when the top ring is lowered the ribs will bend, causing their free ends to droop and stretch the fabric into the form shown in Fig. l of the drawings, in which position, by reason of their resiliency, the ribs will tend to close the shade, causing the top ring to rise and the shade to collapse the instant the spring catches on the rods D are pressed inwardly to release the tubes E. Various other changes may be made in the details of construction and arrangement of parts without departing from the spirit and scope of my invention.

l have thus far described my improvement as applied to an electric lamp, but the same principle and mode of operation may be utilized in lamps of various kinds and of different forms and sizes, for instance, an ordinary lamp with a gas or oil burner.

ln Fig. 3 of the drawings l have illustrated the application of my improvement to a lamp having an oil burner. ln this instance, the general construction and arrangement of parts is substantially the same as described with reference to Figs. l and 2, but a bas-e ring B1 of larger size than that employed in the electric lamp is preferably employed to adapt it to fit over the burner, and the movable top ring C1 is also enlarged and left open to permit the chimney t0 protrude through said top ring, and also to permit the products of combustion to escape and prevent injury to the shade or cover. rlhe base ring B1, to which the lower ends of the stretchers are pivoted, is supported adjacent to the burner by means of a subjacent base ring B2, which fits over the burner and rests upon the oil can and has arms or rods D1 rising therefrom to aord a support for the base ring B1, and continuations or extensions of said rods, or other rods secured upon said base ring, have telescopic connection with the sliding tubes El for interlocking connection with the spring catches thereon, as described with reference to Figs. 1 and 2.

ln Fig. e of the drawings l have illustrated the application of my invention to a lamp having an ordinary gas burner. rllhe construction and arrangement of parts are substantially the same as described with reference to Fig. 3; but instead of a base ring supported on a subjacent ring, which in turn is supported on the oil can or body of the lamp as in Fig. 3, a base ring B3 of spiderlike form is secured on the standard and supports the superstructure comprising a collapsible fabric-covered frame in all material respects substantially the same as the forms shown in Figs. l to 3 and adapted to operate in the same manner.

ln some cases it may be desirable to vary the form of the shade or cover, so as to present a cylindrical appearance, or box-like form, and to this end the stretchers may eX- tend beyond the ribs, as shown in Fig, 5, wherein l have illustrated a modification substantially identical with the form shown in Fig. l, except the form of the cover and the stretchers and their connections with the ribs. ln this instance stretchers J have a pivotal connection intermediate their ends with ribs H so as to provide extensions j the free ends of which may be secured to a cord or rod l connecting said free ends in circular or other form so as to support the cover in the manner shown in said Fig. 6, with its marginal portion depending in straight instead of curved lines and its top approximately flat.

lrVhile l have shown in Fig. 5 the described modiiication as applied to an electric lamp, it is obvious that it may be applied to any ordinary lamp using either an oil or gas burner, by using an open top ring as described with reference to Figs. 3 and 4:.

Having thus described my invention, what l claim as new and desire to secure by Letters Patent is Y l. A collapsible lamp shade comprising two members, one fixed and the other movable toward and from said fixed member, a series of elastic ribs projecting from said movable member, a corresponding series of stretchers each hinged at one end to said Xed member and at the other end to one of said ribs at an intermediate point of the latter, means for securing said movable member in a fiXed position relatively to said fixed member with the shade open, and a lSO suitable cover secured to said ribs in such manner 'that said ribs tend to separate said members and will cause the shade to collapse when said movable member is released to permit the shade to close.
